Abstract:
According to one embodiment, a semiconductor memory device is disclosed. The device includes MOSFET1 and MOSFET2 arranged in a first direction, variable resistive element (hereafter R1) above MOSFET1 and MOSFET2, a lower end of the R1 being connected to drains of MOSFET1 and MOSFET2, MOSFET3 and MOSFET4 arranged in the first direction, variable resistive element (hereafter R2) above MOSFET3 and MOSFET4, and a lower end of the R2 being connected to drains of MOSFET3 and MOSFET4. The device further includes first wiring line extending in the first direction and connected to sources of MOSFET1 and MOSFET2, second wiring line extending in the first direction and connected to sources of MOSFET3 and MOSFET4, upper electrode connecting upper end of the R1 and upper end of the R2, and third wiring line extending in the first direction and connected to the upper electrode.
